Posidyne Clutches Featuring Oil Shear Technology

Eliminate Constant Repair in Severe Duty Applications

The Posidyne Clutch is currently available in two styles, 1. the foot mounted unit which is basically the Posidyne clutch brake with just the clutch stack; and 2. the PTO designed to engage a diesel or gasoline engine to the load.

The standard Posidyne foot mounted clutch is typically used for applications requiring a disconnect clutch, a clutch to engage a large load, or a clutch to engage a very high inertia load requiring a soft start. The Posidyne clutch only can be cooled by basic radiation, fan cooling, water cooling, or forced lube. Forced lube consists of forcing the fluid through the clutch stack continuously using a forced lube cooling unit. This system enables removing vast amount of heat on those high inertia soft start applications.

The PTO is designed to mount to a diesel or gasoline engine to drive various types of stationary systems such as pumps, chippers, mulchers, or crushers. The Force Control PTO offers many advantages such as shorter overall length, high capacity, unique cooling system, and can incorporate a brake to slow a high inertia drum such as used on chippers. It also has an additional pump option providing a drive system for up to 4 hydraulic pumps.

The clutch is engaged by compressing a multiple disc friction stack using either air or hydraulic pressure. The pressure determines the torque transmitted through the clutch.

Transmission fluid circulating through the unit flows through an open center hub, through the friction stack, and out to the housing. Cooling occurs as the fluid runs back to the bottom of the unit to be recirculated. This system, called Oil Shear Technology, prevents wear on the friction surfaces, removes heat from the friction area to the housing, and lubricates all internal parts.
